Interface DependencyGraphTransformer
-
public interface DependencyGraphTransformer
Transforms a given dependency graph.Note: Implementations must be stateless.
Warning: Dependency graphs may generally contain cycles. As such a graph transformer that cannot assume for sure that cycles have already been eliminated must gracefully handle cyclic graphs, e.g. guard against infinite recursion.

transformGraph
DependencyNode transformGraph(DependencyNode node, DependencyGraphTransformationContext context) throws RepositoryException
Transforms the dependency graph denoted by the specified root node. The transformer may directly change the provided input graph or create a new graph, the former is recommended for performance reasons.- Parameters:
node
- The root node of the (possibly cyclic!) graph to transform, must not benull
.context
- The graph transformation context, must not benull
.- Returns:
- The result graph of the transformation, never
null
. - Throws:
RepositoryException
